Entsprechend einem weiteren Kennzeichen umfassen die vorher erwähnten Sensormittel ein axial nachgiebiges Element, wirksam zwischen das Ende des gestreckten Formgedächtniselements und das gesteuerte Bauteil gesetzt, wobei das nachgiebige Element gestaltet ist, um beim Überschreiten des Schwellenwerts der axialen Last axial nachzugeben, so dass die Bewegung des Endes des gestreckten Elements nicht auf das gesteuerte Bauteil übertragen wird, wenn die darauf aufgebrachte Last den vorher festgelegten Schwellenwert überschreitet.Corresponding another feature includes the aforementioned sensor means an axially compliant element, effective between the end of the stretched Shape memory element and the controlled component set, wherein the compliant element is designed to be exceeded axially yielding the threshold of the axial load, so that the Movement of the end of the stretched element not on the controlled Component is transmitted, when the load applied thereto exceeds the predetermined threshold.
Entsprechend einem weiteren vorgezogenen Kennzeichen ist das vorher erwähnte nachgiebige Element eine Feder, vorzugsweise eine Schraubenfeder, die axial zwischen einem ersten Körper, verbunden mit dem Ende des Formgedächtniselements, und einem zweiten Körper, wirksam verbunden mit dem gesteuerten Bauteil, gesetzt ist.Corresponding Another preferred feature is the previously mentioned compliant element a spring, preferably a coil spring, axially between a first body, connected to the end of the shape memory element, and a second Body, effectively connected to the controlled component.
In der bevorzugten Ausführungsform umfasst die Betätigungseinrichtung weiterhin Mittel zum Unterbrechen der elektrischen Versorgung des Formgedächtniselements, wenn die Sensormittel ein Überschreiten des Schwellenwerts der axialen Last auf das Formgedächtniselement wahrnehmen. Die Mittel zum Unterbrechen der elektrischen Versorgung umfassen vorzugsweise einen elektrischen Kontakt, eingesetzt in den Versorgungsschaltkreis und bestehend aus zwei Kontaktelementen, die sich voneinander wegbewegen, wenn das nachgiebige Element bei Überschreiten des vorher beschriebenen Schwellenwerts der axialen Last nachgibt.In the preferred embodiment includes the actuator furthermore means for interrupting the electrical supply of the shape memory element, if the sensor means an exceeding the threshold value of the axial load on the shape memory element perceive. The means for interrupting the electrical supply preferably comprise an electrical contact inserted in the supply circuit and consisting of two contact elements, which move away from each other when the compliant element passes yields the previously described threshold of the axial load.
Nochmals in dem Falle der vorher erwähnten bevorzugten Ausführungsform wird ein erstes Kontaktelement des elektrischen Kontakts getragen durch einen ersten Körper, verbunden mit dem Ende des Formgedächtniselements, das zweite Kontaktelement wird durch einen zweiten Körper getragen, wirksam verbunden mit dem gesteuerten Bauteil, so dass beim Nachgeben des nachgiebigen Elements während der Aktivierung des Formgedächtniselements der erste Körper in Bezug zu dem zweiten Körper versetzt wird, was zu einem Unterbrechen des elektrischen Kontakts führt.again in the case of the aforementioned preferred embodiment a first contact element of the electrical contact is carried by a first body, connected to the end of the shape memory element, the second Contact element is supported by a second body, effectively connected with the controlled component, so that when yielding to the yielding Elements during the activation of the shape memory element the first body in relation to the second body is offset, resulting in a break in the electrical contact leads.
Entsprechend einem weiteren bevorzugten Kennzeichen gibt es weiterhin voraussehende Mittel zur Regulation der Last auf die vorher erwähnte Feder zu dem Zweck einer Regulation des Schwellenwerts, bei welchem die Einrichtung zum Unterbrechen der elektrischen Versorgung des Formgedächtniselements auslöst. Die letztere kann aus einem einzelnen Formgedächtnisdraht bestehen oder aber ebenso aus einer Vielzahl gestreckter Elemente, z.B. einer Vielzahl von Formgedächtnisdrähten, die parallel zueinander angeordnet sind.Corresponding Another preferred feature is still anticipatory Means for regulating the load on the aforesaid spring for the purpose of regulating the threshold at which the Device for interrupting the electrical supply of the shape memory element triggers. The latter may consist of a single shape memory wire or else as well from a plurality of elongated elements, e.g. a variety of Shape memory wires that are arranged parallel to each other.
Weitere Kennzeichen und Vorteile der Erfindung werden aus der folgenden Beschreibung in Bezug zu dem beigefügten Satz von Zeichnungen ersichtlich, welche rein als nichtbeschränkende Beispiele gestaltet sind und in welchen:Further Features and advantages of the invention will become apparent from the following Description in relation to the attached set of drawings, which purely as non-limiting Examples are designed and in which:
In
Bezug zu
Es
gibt betrachtete Standards, die den Hersteller zwingen, die Möglichkeit,
das Schloss manuell vom Inneren des Fahrzeugs zu bedienen, in Betracht zu
ziehen, um eine Person, die unabsichtlich in dem Motorfahrzeug eingeschlossen
geblieben ist, in die Lage zu versetzen, die Heckklappentür zu öffnen. In dem
gezeigten Beispiel kann der Betätiger
manuell bedient werden durch einen Ring
In
dem Fall, anstatt elektrischer Betätigung, bleibt die Hülse
Der Vorteil, die Hülse der Betätigungseinrichtung als ein Element zur mechanischen Übertragung zu verwenden in dem Fall manueller Betätigung, besteht in der Tatsache, dass es auf diese Art immer möglich ist, Betrieb der Einrichtung zu garantieren, auch in dem Fall unabsichtlichen Versagens des flexiblen Formgedächtniskabels.Of the Advantage, the sleeve the actuator to use as an element for mechanical transmission in the case of manual operation, consists in the fact that in this way it is always possible Operation of the device to guarantee, even in the case of unintentional Failure of flexible shape memory cable.
Es
mag bekannt sein, dass in dem Fall der vorher vorgeschlagenen Lösung (in
In
dem Fall der Lösung,
welche auch schon vorgeschlagen wurde (gezeigt in
Die
Beschichtung
Die Gestaltung des Formgedächtniskabels kann alles Mögliche sein. Es ist weiterhin möglich, eine Anzahl Formgedächtniskabel innerhalb derselben Beschichtung zu extrudieren, parallel zueinander angeordnet. Ebenso möglich ist eine U-förmige Kabelgestaltung mit einem ansteigenden Ast und einem absteigenden Ast und die zwei Enden des Kabels einander gegenüber, welche unter anderem den Vorteil ermöglicht einer passenden elektrischen Verbindung des Kabels mit den elektrischen Versorgungsmitteln.The design of the shape memory cable can be anything. It is also possible to have a number of shape memory cables within the same To extrude coating, arranged parallel to each other. Also possible is a U-shaped cable design with a rising branch and a descending branch and the two ends of the cable opposite each other, which, inter alia, the advantage of a suitable electrical connection of the cable with the electrical supply means.
In
Betrieb
der Einrichtung wird im Folgenden beschrieben. Wenn die elektrische
Zufuhr aktiviert ist, werden die zwei Strecken des Formgedächtnisdrahts
Dank der vorher erwähnten Anordnung wurde folglich ein Schutz der Formgedächtnisbetätigungseinrichtung erhalten gegen übermäßige mechanische Span nungen und gegen eine übermäßige elektrische Zufuhr. Die Unterbrechung der elektrischen Zufuhr begründet die Rückkehr des Formgedächtniselements in seine Ruhestellung.thanks the previously mentioned Arrangement was thus obtained a protection of the shape memory actuator against excessive mechanical Voltages and against excessive electrical Supply. The interruption of the electrical supply justifies the return the shape memory element to his rest position.
Natürlich, ohne Präjudiz zu den Prinzipien der Erfindung, können die Details der Konstruktion und die Ausführungsform weit variieren in Abhängigkeit zu dem, was hier beschrieben und gezeigt wurde rein als Beispiel, ohne dabei den Bereich der vorliegenden Erfindung, wie durch die Ansprüche definiert, zu verlassen.Of course without precedent Among the principles of the invention, the details of the construction and the embodiment vary widely depending to what was described and shown here purely as an example, without departing from the scope of the present invention as defined by the claims defined, leave.
